It still brings the type of some fields or the constraints. However need of specifying "poll-interval" already points to missing unevaluatedProperties. Best regards, Krzysztof

Ok, this wasn't clear for me wether or not I should pick unevaluatedProperties as I still reference "poll-interval" from the input.yaml schema ?

You should drop it from your binding. Best regards, Krzysztof

Because it comes from input.yaml and you did not add any constraints, so poll-interval here is redundant. Best regards, Krzysztof
